Definitions
- the present invention relates generally to window coverings of the type often installed externally on domestic or commercial buildings. More specifically, the invention relates to a multifunction awning that can transform to become a vertical blind to completely cover a window. It will be convenient to describe the invention relation to that example application. It should however be understood that the invention is capable of broader application and use.
- Awnings and blinds are often installed on windows of a building to shade the window from the sun.
- Awnings have an advantage in that they generally extend outward from the building and provide shade while enabling views.
- vertical blinds can completely cover the window and, while they provide maximum protection from the sun at all times of day, including afternoon sun when at its hottest, they restrict the view.
- the blind fabric is wound on a roller (often mounted within a header box or pelmet at the top of the window) that is spring-loaded such that the blind fabric automatically retracts onto the roller when released.
- the bottom rail of the blind is fixed to a relatively short pair of arms that slide vertically along guide rails mounted either side of the window.
- the blind is moved up and down by twisting the bottom rail, to release the arms from a locked position on the guide rails, by hand or using a rod and hook inserted within a ring provided on the bottom rail.
- the blind is then manually pulled down or pushed up by hand. Being completely manual in operation restricts the use of auto blinds to situations where the blind can be reached - installations above ground floor level, such as on a second or higher floor of a building, are generally not possible.
- Another known type of vertical blind capable of completely covering a window is a retractable straight drop blind.
- the blind fabric is again wound on a roller that is spring-loaded such that the blind fabric automatically retracts onto the roller.
- the bottom rail of the blind is held between two guide rails or wires, and it slides up and down along the guides.
- Such a blind may be manually operated or motorised.
- a known form of window awning is generally referred to as a “retractable fixed pivot arm awning” or “drop arm awning”.
- These awnings are somewhat similar to the auto blind described above, in that they have a blind fabric wound on a roller and a bottom rail of the blind is fixed to a pair of arms. However, the arms are mounted in fixed positions to the wall of the building alongside the window opening. The arms are spring biased such that they are caused to rotate about their fixed mounting positions as fabric from the roller is unwound, either manually using a crank handle arrangement or motorised. To provide sufficient coverage for a whole window, the arms must generally be much longer than would be required for an auto blind.
- each arm would need to be at least 1 .2 meters long. This length is inconvenient and potentially dangerous in many installations, for example alongside a footpath or driveway where it would impede passage of pedestrians or vehicles when the arm is extended horizontally.
- awning is a retractable folding arm awning that extends horizontally, or at predetermined angle below the horizontal, from the building wall above the window opening. This type of awning provides shade over a window but is not capable of controlling its angle of projection to vertically protect the window. [0007] With the foregoing in mind, it would be desirable to develop a convertible window covering which, on the one hand, can act as an awning when the sun is high in the sky and, on the other hand, act as a vertical blind to completely cover a window when required.
- the present invention provides a multifunction awning blind for a window or similar opening in a wall of a building.
- the awning blind comprises: a blind roller configured to be secured to the wall at the top of the window opening; a blind fabric wound upon the blind roller such that the blind fabric can be wound and unwound from the roller; a bottom rail secured to a free end of the blind fabric; a pair of side rails configured to be secured to the wall with one rail on each side of the window opening; a pair of slider assemblies attached to and movable along respective side rails; and a pair of side arms, each arm having a first end pivotally connected to a respective slider assembly about a pivot axis and being spring biased to pivot about the axis such that a second end of the arm is urged outwardly away from the window and downward away from the blind roller, and each arm having its second end fixed to the bottom rail such that unrolling the blind fabric allows each arm to pivot about its axis, whereby, in use, unrolling the blind fabric up to a
- the length of the side rails, the length of the side arms and amount of blind fabric provided on the roller together enable the blind to fully cover the window when in the lowermost position .
- the side arms may be between about 300mm and 500mm in length, and the side rails may be between 1 ,0m and 2.0m in length.
- any alternative arm and rail lengths may be chosen according to the size of the window opening and any other installation requirements or restrictions. Such variations would be readily apparent to a person skilled in the art and need not be explained in detail.
- the amount of blind fabric provided on the roller is then selected as required for the installation.
- end stops may be provided at one or both ends of each side rail to limit the range of travel of the slider assemblies along the side rails.
- each slider assembly comprises a front portion and a rear portion.
- the front portion is preferably configured to enable the respective side arm to be pivotally connected to the slider assembly.
- the rear portion is preferably configured to enable the slider assembly to travel along the respective side rail.
- each slider assembly comprises at least one linear bearing to enable the slider assembly to travel along the respective side rail.
- the rear portion of the slider assembly comprises a pair of linear bearings.
- Each linear bearing preferably comprises a bush carrying rows of rollers held by a retainer, with each linear bearing being secured within the rear portion by a cradle.
- the cradle and linear bearing are split lengthwise such that a lengthwise aperture is formed to allow the rear portion of the slider assembly to travel past a mounting bracket securing the side rail to the wall of the building.
- each side arm is spring biased by a spring and cable arrangement located within the side arm.
- the spring and cable arrangement produce a twisting action between the linear bearing(s) and the respective side rail such that, in use, the twisting action substantially prevents the slider assembly travelling downwards along the respective side rail until the blind fabric is unrolled beyond the second amount. Beyond that amount, the twisting action is relieved and the slider assembly becomes free to travel downwards along the respective side arm.
- the front portion of the slider assembly comprises a forwardly projecting plate with a transverse aperture to enable the respective side arm to be connected thereto and to pivot about the pivot axis passing through the aperture.
- the front portion of the slider assembly is secured to the rear portion by means of a pair of fasteners which secure the two portions together.
- the front portion and rear portion of the slider assembly may be integrally formed.
- the bottom rail may be weighted to assist in providing smooth travel of the slider assemblies along the respective side rails.
- the blind roller may be motorised to enable the awning blind to be remotely controlled. This can be convenient in many installations.
- Figures 1 A-1 C show front perspective, front elevation and side cross- sectional views, respectively, of a blind awning in accordance with a preferred embodiment the invention, in a fully retracted (i.e. fully open) position.
- Figures 2A-2C show front perspective, front elevation and side cross- sectional views, respectively, of the blind awning of Figures 1 A-1 C in an extended position where the side arms extend horizontally.
- Figures 3A-3C show front perspective, front elevation and side cross- sectional views, respectively, of the blind awning of Figures 1 A-1 C in a further extended position where the arms project downwardly (although noting the front and side views of Figures 3B and 3C show the slider assembly and side arms in a slightly lower position than in the perspective view of Figure 3A).
- Figures 4A-4C show front perspective, front elevation and side cross- sectional views, respectively, of the blind awning of Figures 1 A-1 C in a fully extended (i.e. fully closed) position where the arms project downwardly and are located at the bottom of the side rails such that the blind fabric completely covers the window.
- Figures 5A and 5B show front and rear perspective views, respectively, of a slider assembly in accordance with one embodiment of the invention.
- Figures 6A-6E show front, side, rear, top and bottom views of the slider assembly shown in Figures 5A-5B.
- Figure 7 shows an exploded perspective view of the slider assembly shown in Figures 5A-5B.
- Figure 8A and 8B show front and side cross-sectional views, respectively, of a side arm, slider assembly and side rail in accordance with one embodiment.
- FIG. 1 A to 4C there is shown a multifunction awning blind 10, in accordance with a preferred embodiment of the invention, for a window 12 or similar opening in a wall 14 of a building.
- a window or similar opening in a wall 14 of a building.
- the awning blind 10 comprises a blind roller 16 configured to be secured to the wall 14 at the top of the window opening 18.
- the roller 16 is located within a protective header box 20.
- the awning blind 10 also comprises a blind fabric 22, a bottom rail 24, a pair of side rails 26, a pair of slider assemblies 28, and a pair of side arms 30.
- Figures 1 A-1 C show the awning blind 10 in a fully retracted (completely open) position.
- Figures 2A-2C show the awning blind in an extended position with its arms 30 projecting horizontally such that the blind fabric 22 forms a canopy or hood over the window 12.
- Figures 3A-3C show the awning blind in a further extended position with the arms 30 projecting downwardly
- Figures 4A-4C show the awning blind in a fully extended position with the arms 30 again projecting downwardly but now shifted downward towards the bottom of the side rails 26 such that the blind fabric 22 is substantially vertical (Figure 4C) and completely covers the window 12.
- the blind fabric 22 is wound upon the blind roller 16 such that the fabric can be wound and unwound from the roller.
- the bottom rail 24 is secured to a free end of the blind fabric 22 and the pair of side rails 26 is configured to be secured to the wall 14, with one rail on each side of the window opening 18.
- the slider assemblies 28 are attached to and can slide up and down along respective side rails 26.
- Each side arm 30 has a first end 31 pivotally connected to a respective slider assembly 28 and is spring biased to pivot about an axis such that a second end 3T of the arm (i.e. its free end) is urged outwardly away from the window 12 and downward away from the blind roller 16.
- Each arm 30 has its second end 31 ’ fixed to the bottom rail 24 such that unrolling the blind fabric 22 allows each arm 30 to pivot about its axis.
- the awning blind 10 may be manually operated using a crank arm, or it may be motorised such that a user can operate the awning blind remotely.
- the user controls rotation of the blind roller 16 to allow the blind fabric 22 to be unrolled from the roller.
- This causes the arms 30 to extend outward, away from the wall 14, such that the blind fabric 22 forms a canopy over the window 12.
- This outward extension continues until the blind fabric 22 is unrolled a “first amount” and the arms 30 reach a horizontal position, 90° to the side rails 26, as shown in Figure 2A-C.
- the “first amount” thus corresponds to the length of blind fabric unwound from the roller for the arms to reach the horizontal position.
- the operation of the awning blind 10, with side arms 30 pivoting between the fully up position shown in Figures 1 A and the down position shown in Figures 3A is similar to the operation of a conventional retractable fixed pivot arm awning, as described in the Background section above.
- the awning blind of the present invention may be further unrolled to allow the blind to drop down to any length according to the amount of material that is provided on the blind roller.
- the side arms 30 may be made of any length and need not be made half the height of the window to achieve full coverage, as in a conventional fixed pivot arm awning. Choosing shorter arm lengths minimises obstructions where windows are located close to footpaths or driveways.
- the arms may, for example, be made 500 mm in length and still achieve full coverage of a 2 m window by providing side rails having a 1 m length of travel.
- the arms may be only 300 mm in length and be combined with rails having a 1 .4 m length of travel to achieve the same 2 m window coverage.
- the lengths of the arms and rails may therefore be chosen according to the intended application and window position.
- the length of the arms may also be chosen to achieve any desired horizontal projection (when in the 90° horizontal position, as in Figure 2) of the canopy/hood formed over the window. In some situations, a deeper canopy may be desired whereas in other situations a shallower canopy is better.
- FIG. 5A to 7 there is shown a slider assembly 28 in accordance with an embodiment of the invention.
- Figures 5A and 5B show front and rear perspective views respectively
- Figures 6A-6E show various elevations
- Figure 7 shows an exploded perspective view in which various components of the slider assembly are separated.
- the slider assembly 28 includes a front portion 50 and a rear portion 52.
- the front portion 50 has a forwardly projecting plate 54 having an aperture 56 to enable a side arm 30 to be connected thereto and enable the arm to pivot about an axis passing through the aperture 56.
- the front portion 50 is secured to the rear portion 52 by means of a pair of fasteners 58 (in this instance hexagonal socket head cap screws) which secure the two portions together. Locating bosses 60 are provided to precisely position the front portion 50 relative to the rear portion 52.
- the front portion 50 and rear portion 52 may be integrally formed as a single piece. The provision of two separate components is not essential.
- the front portion 50 includes means to anchor a tension cable 62 for a spring 64 located within the arm 30 (see Figure 8B).
- an aperture 66 and guide slot 68 are provided to enable the tension spring 62 to be anchored beneath the front portion 50, pass through the aperture 66 and along the guide slot 68, over the front of the projecting plate 54 and then enter the arm 30 and connect to the spring 64.
- the tension provided by the spring 64 on the tension cable 62 pulls the arm 30 downwards, towards the position shown in Figures 3A-3C.
- the rear portion 52 includes a pair of linear bearings 70 to enable the slider assembly 28 to smoothly travel along a side rail 26.
- Each linear bearing 70 comprises a bush 72 carrying rows of rollers 74 held by a retainer 76.
- Each linear bearing 70 is secured within the rear portion 52 by a cradle 78, as best seen in Figure 5B. Both the cradle 78 and linear bearing 70 are split lengthwise such that a lengthwise aperture is formed to allow the rear portion 52 of the slider assembly 28 to travel past mounting brackets 80 that secure the side rails 26 to the wall of the building. Two sets of bearing locking pins 82 ensure that the linear bearings 70 do not move lengthwise within their respective cradles 78.
- FIG 8A there is shown a front view of side arm 30 attached to and movable along a side rail 26 by means of a slider assembly 28.
- a pivot pin 79 passing through the aperture 56 in the plate 54 secures the arm 30 to the slider assembly 28.
- the mounting bracket 80 that secures the side rail 26 to the wall 14 of the building.
- Figure 8B shows a cross-sectional side view of this arrangement along the line B-B in Figure 8A. In this view, one can see the tension cable 62 held by a swaged end 84 within a recess provided in the underside of the body of the front portion 50.
- the spring 64 is a compression spring located within a hollow body of the arm 30 and the tension cable 62 is secured to the far end of the compression spring by a retainer 86.
- the retainer 86 is not fixed to the arm 30 and is instead free to move lengthwise within the inner cavity of the arm.
- the spring 64 could instead be a tension spring fastened at some point within the arm 30, such as at or near its free end.
- tension on the cable 62 by the spring 64 serves to cause the arm to want to rotate about an axis passing through the pivot pin 79, in an anticlockwise direction in this figure.
- the multifunction awning blind of the present invention has significant advantages over conventional awnings and blinds. It can serve both functions in accordance with the amount of blind fabric released from the roller. These different functions can be employed in different situations or at different times of the day.
- an awning window (a window of the type that hinges from the top) can be opened to let in airflow with the blind down, thus providing protection from the sun, wind and rain.
- the blind With the awning blind in a halfway position the blind becomes a hood awning, or canopy, that solves the problem of high sun penetration while allowing the unaffected portion of the window to be free, thus allowing shade while maintaining the view and airflow through an open window.
- Embodiments of the awning blind of the present invention provide these advantages by being able to “transform” between awning and blind functions.
- the awning blind may be motorised so that it can be remotely controlled. This overcomes a problem for elderly people trying to use conventional auto blinds, of the type described in the Background above, when trying to use a rod to manually move the auto blind up-and-down.
- a motorised blind can also be operated by anyone remotely in difficult to reach applications and multilevel buildings. It may also be operated from inside the building, eliminating the need to go outside in the case of wind, rain, or if the blind is in a hard to reach location.
